Single_cat_title() print the title before text

Question

When I use single_cat_title() get the name of the current category in archive page, it works perfectly but it prints the category title before the text

<h2>
    <?php 
        if (is_category()){
            echo 'Category: ' . single_cat_title();
        }
    ?>
</h2>

It says:

UncategorizedCategory:

How do I fix it? Thank you.

Answer 1

Set the display argument of the function to false.

<h2>
    <?php 
        if (is_category()){
            echo 'Category: ' . single_cat_title( '', false);
        }
    ?>
</h2>

Or, to use the function in its more "helpful" form you could do:

single_cat_title('Category: ');

If the display argument is true, WordPress automatically echoes the content on to the page usually within a wrapper html element and this messes with your echo.
